  • Patent number: 10124607
    Abstract: A printing apparatus comprises: a printer that includes a printing mechanism that performs printing on a printing medium, the printing mechanism being provided in a print area; a housing that includes an opening region for exposing the printing mechanism to outside; and a guiding mechanism that represents a position of the print area. The guiding mechanism is provided at a position directly above the print area and visible from outside. Accordingly, when a user performs printing on the printing medium using this printing apparatus, the user can easily grasp a position of the print area by means of the guiding mechanism, and therefore can print on a desired position on the printing medium.

  • Patent number: 9446585
    Abstract: A handheld inkjet printer includes an inkjet print head and a tip. One or more sensors measure the position of points on a curved surface that are physically touched by the tip while the tip is moved relative to the surface. Based on these measurements, a computer generates or modifies a computer model that specifies at least (i) position of the curved surface, and (ii) a target region of the curved surface on which a pattern is to be printed. In addition, the one or more sensors measure position and orientation of nozzles in the print head, while the handset is moved relative to the surface. The computers also calculate, based on the computer model and these additional measurements, which of the nozzles to fire at a different times, such that the pattern is printed on the target region as the handset is moved relative to the surface.

  • Patent number: 6942335
    Abstract: A hand held device that accepts a digital image, and transfers it to a wall, ceiling, floor, or any smooth surface. The hand held unit consists of a print element array in addition to a positioning mechanism that determines the absolute position of said device on the wall. Said positioning mechanism consists of a plurality of extruding tape, which in conjunction with the motion of the device over the surface, provides linear measurements from a plurality of fixed reference points to a fixed location on the device. The combination of said tapes provide sufficient information to triangulate the exact location and orientation of said device on the surface, subsequently providing sufficient information to impart the proper portion of said digital image to the surface, as said device moves across the surface. Repeated sweeping movements of said device over the surface will render further portions of the image, until it is complete.

  • Patent number: 6773177
    Abstract: A method and system for position-aware freeform printing in which a source image space in a source medium and a target image space in a target medium are specified. A selected image in the source image space is copied and/or optionally processed and transferred to the target image space. A controller captures the selected source image and stores the image in a memory. The image is optionally processed and the processed and optionally formatted image is output. The controller may format the processed image to fit into the target image space by controlling the rendering of the processed image onto the target medium as the printing device is moved over the target image space in a freeform direction. The controller predicts the freeform direction that the print head will travel by detecting the motion previously traveled and adjusting the image to compensate for the predicted freeform direction.

  • Publication number: 20040109034
    Abstract: A hybrid printing device for printing on a surface, the device comprising a printing means adapted to print on the surface and a sensing means adapted to sense the position of the printing device in relation to positioning indicia located on the surface wherein the printing means is further adapted to be responsive to the detected position of the device in relation to the detected position. The device operates by detecting the position whereby a print control means responds and signals to the printing head to function to build the image on the printing surface. The invention preferably uses optical glyphs pre-printed on the page to provide position information to the sensing means. The device may operate as a peripheral where the print head is controlled in response to the detected position. Alternatively, the print head may be triggered by print control data itself embedded in the optically detected glyph information.

  • Patent number: 6618078
    Abstract: A method and apparatus for capturing and printing an image of a subject utilizes a tracking mechanism to allow an operator to print the captured image onto a selected surface by manually manipulating the apparatus across the surface. The apparatus is a print-capable digital camera which can print the captured image in one of a range of sizes. The printing process involves an operator placing the digital camera on the surface and scanning the surface in order for the digital camera to print a segment of the captured image according to the location of the digital camera. The tracking mechanism may be comprised of two trackball assemblies. The rotations of the trackballs generate location data which is utilized by digital signal processing circuitry to determine the position of the digital camera relative to a start-print position.

  • Patent number: 4436439
    Abstract: A small printer for printing characters on a printing medium especially adapted for use in a portable electronic calculator. The printer includes a frame having a carriage slidably mounted thereon for lateral displacement across the printing medium. An ink jet printing mechanism is carried on the carriage for selectively printing characters at predetermined positions along lines of the printing medium. A crank mechanism couples a motor to the carriage so that the printing mechanism can be translated across the printing medium. A printing position control circuit determines when the printing mechanism is in each predetermined printing position and selectively supplies a printing signal to the printing mechanism so that the printing mechanism will print a character at the selected predetermined positions.

  • Patent number: 4211012
    Abstract: A character applying device which is controlled by a separate signal processor can be manually moved across a writing surface while the characters are being applied. A single-tipped marking instrument is moved with a prescribed motion parallel to the surface as the device is moved across the surface to create a relatively dense array of line patterns. Simultaneously, received control signals cause the tip to move in and out of contact with the surface for, in effect, masking the array to produce characters represented by those signals.

  • Patent number: 4165513
    Abstract: A marking device includes a case which may be held by a user in the fashion of conventional writing and marking instruments. A ball point pen, felt tip pen, pencil or crayon is positioned within the case. In the instances of the pens, a soft iron collar is fixed or adjustably connected to the pen. In the instances of the pencil or crayon, a movable, hollow, soft iron collar is positioned about the pencil or crayon, a plurality of balls of non-magnetic, non-magnetizable material are provided within the collar to hold the pencil or crayon in fixed, preferably adjustable, position when the collar is moved downwardly. An electro-magnet or solenoid responsive to electrical signals or pulses is placed in the vicinity of the fixed or movable soft iron collar.
